CORNER CLEAT.

APPLICATION FILED MAY 6. 1920.

FPederic/r W. Lord FREDERICK W. LORD, OF NEW Ff WEW? e f-aha; at wil ti a ewiifiu N. Y., ASSIGNOR TO LORD MANUFACTURING CORNER CLEAT.

Application filed May 6, 1920.

To all whom it may concern Be it known that I, FREDERICK W. Loni), a citizen of the United States, and resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Corner Cleats, of which the following is a specification.

This invention relates to improvements in corner cleats for securing together the corners of picture-frames and the like, and has for its principal object to provide a cleat adapted to be used principally in connection with mitred joints which, when driven into place will cause the abutting edges of the mitre to firmly engage each other, so as to eliminate the necessity of using glue or a similar adhesive.

Another object of the invention resides in the provision of a corner cleat which may be stamped from a single piece of material, thereby permitting the devices to be made in quantities at a reasonable cost.

A further object of the invention is to provide a substantially L shaped cleat having points arranged in parallel rows which in turn are parallel to the mitre, so that when the device is driven into place the points act against the adjacent bars of the frame to prevent their separation.

Still another object of the invention is to provide a device having the points of one leg inclined in a direction opposite those carried by the other leg, in such a mann r that when the device is driven into place the points will co-act in drawing the adjacent bars of the frame together.

With these and other objects in view, the invention consists of a novel construction, combination and arrangement of parts which will be fully set forth in the following specification, claimed and illustra ed in the accompanying drawings in which Fig. 1, is a fragmentary view of a frame showing this device in use.

Fig. 2, is a perspective view of the corner cleat and Fig. 3, is a sectional view on line 33 of Figure 1., showing the inclination of the points whereby the bars are drawntogether.

Specification of Letters Patent.

Patented Jan. 3, 1922.

Serial No. 379,299.

Referring to the drawings in detail, the numeral 5 designates one bar of a frame, while the numeral 6 designates the adjacent bar of the frame. The abutting ends of each bar are mitred as illustrated in Figure 1, and the usual screening material 7 is secured in the frame in an ordinary manner.

The corner cleat is designated in its entirety by the numeral 8 and constitutes a substantially l. shaped body having legs 9 and 10 arranged at right angles to each other, and provided with suitable openings or s rew-receiving apertures 11 for the re ception of attaching screws 12 which form an auxiliary securing means for the device.

Strir'k from the legs of the L shaped body are parallel rows or points and as shown in Figure 3 the points 13 of the leg 9 incline downwardly and outwardly away from the point where the legs join. The points 14 of the leg 10 incline downwardly and outwardly in a direction opposite to the inclination of the points 13 and it will be noted upon reference to the drawings that the points are arranged in parallel rows with their fiat faces in planes'parallel to the mitre.

In use the frame bars 5 and 6 are cut in the manner shown in Figure 1 and the corner cleat is then placed on the bars and it will be seen that u on driving the cleat into place the points will a t to draw the abutting ends ofthe bars into firm contact, thus makinc; a tie'ht joint. After the cleat has been driven into place the screws 12 are introduced through the openings 11 and driven home. and it will be seen that the frame will be rmly se u ed together.

lVhile in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that certain minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

lVhat'I claim is The combination with a frame comprising frame bars mitre d at their ab utting ends, of a one piece construction corner cleat comprising a substantially L shaped body and being inclined in the opposite direction parallel rows of points struck from the body whereby When the device is driven into place in planes parallel with the mitred ends of the frame bars Will be drawn together.

the frame bars, the points in one leg being Signed at New York city, this 23rd day 10 5 inclined downwardly and outwardly from of April, 1920.

the body and the points in the other leg FREDERICK W. LORD.
